To create more subnets, you can use subnetting, which involves dividing a larger network into smaller, manageable segments. This is achieved by borrowing bits from the host portion of an IP address to create additional network bits, effectively increasing the number of available subnets. For example, if you start with a /24 subnet and borrow 2 bits, you can create 4 additional subnets with a /26 prefix. Ensure that the subnet mask and addressing scheme align with your network design and requirements.
Depending on class of network you are planning to use. For class C you can create much more then that (and for the most case for others too).
5 bits are necessary to create up to 30 subnets.

Subnets allow to isolate traffic within a subnet. It is beneficial not only from security perspective but also from performance.

To create 8 subnets for the IP address 192.168.1.0, you need to use subnetting. Since 8 subnets require 3 additional bits (as 2^3 = 8), you can take 3 bits from the host part of the default subnet mask (255.255.255.0 or /24). This will change the subnet mask to 255.255.255.224 (/27), allowing for 8 subnets, each with 30 usable host addresses (2^5 - 2 = 30). The resulting subnets will range from 192.168.1.0 to 192.168.1.224.
To create 6 subnets from the IP address 172.16.0.0, you need to determine how many bits to borrow from the host portion of the address. Since 2^3 = 8, borrowing 3 bits allows for 8 subnets, which is sufficient for your requirement of 6. This results in a subnet mask of 255.255.248.0 (or /21), providing each subnet with 2046 usable host addresses. The subnets would range from 172.16.0.0/21 to 172.16.7.0/21.
When you borrow 3 bits from the host portion of an IP address, you can create (2^3 = 8) valid subnets. However, one subnet is reserved for the network address and another for the broadcast address, leaving you with 6 usable subnets. Thus, by borrowing 3 bits, you obtain 6 valid subnets for use.
